rIhis invention relates to an improved construction of hollow tiles usedin the construction of iioors, the general object of the invention beingto provide means for strengthening a ioor formed of concrete and tofacilitate the construction of the Hoor.

Another object of the invention is to p-rov 1@ provide means on thetiles which will facilitate the leveling of the concrete as such meanson the tiles form guides or screeds for the leveling members.-

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts,

to be hereinafter fully described, illustrated ly pointed out in theappended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which Figure lis a sectional view showing how the tiles are used in the constructionof a concrete lioor. 1

In that form of the invention shown in Figures 1 and 2, the tile 1 isformed with a fiat bottom, tapered side edges and a fiat top which isformed with a longitudinal rib 2. The tile is formed of reproof materialand is of such anature that a nail or the like can be driven into thesame. In use, the tiles are 4REISSUED f 1930. Serial No. 464,989.

set on the strips 3 supported by the upright frame 4, the strips 3forming portions of the floor mold and in order to evenly space thetiles apart in the rows, I provlde a spacer strip v5 .which is placed onthe strip 3 against the row of tiles which has already been laid so thatanother row of tiles can be placed against the strip 5, as shown inFigure 1.l The strip 5 is then removed and the concrete 6 is poured onthe tiles and between the spaces between the rows of tiles after thereinforcing rods 7 are put in place. The rods 2 form guides or screedsfor the leveling board which is used to level the concrete after thesame has been put in place. When the concrete hardens, the concrete andthe tiles form a floor or horizontal partition and when a flooring 8 ofwood or the like is to be laid on the concrete floor, this iooring canbe nailed to the ribs 2 on which it rests, as shown in Figure l.

Figures 3 and fl show a tile 1 which is formed without the rib 2 andthis tile is also formed with the iianges 9 at the lower parts of itssides. The flanges of one tile will abut those of another, as shown inFigure 3 so that these tiles are selispacing and the use of the spacerstrip 5 is not necessary. With the use of the tiles shown in Figures 3and 4,

the entire ceiling is formed bythe base arts.

ormsthese tiles are separated the same as the tiles shown in Figures 1and 2.

Figures 7 and 8 show a tile 1Il which is provided with both the rib 2and the angs 9 so that this tile combines the features of the tilesshown in Figures l and 2 and 3 and 4. Figure 9 shows how the tiles ma beformed with two cores 10 instead of a single core, as in the otheriigures. Of course, the tile can be formed of any internal shape, asdesired. n p

The improved tiles facilitate the laying of concrete floors, as thetiles form portion of the forms for receiving the, concrete and a. solid'bottom fora form is not necessary, as

it is simply necessary to provide means for supporting the tiles andwhen the tiles are spaced apart as in Figure 1, the members 3 are simplyused to close the bottom of the spaces between the rows of tiles. Whenthe tiles having the ribs thereon-are used, the ribs form iding meansfor the leveling board and a so as supports forflooring or the likewhich can be nailed to the ribs. The

-exposed baseA ortions of the tiles can also have ceiling or-ming:meansor any other means attached thereto by nails or the like. Thetiles may be formed of cinder concrete or any other suitable'materialwhich will permit nails or the liketo be driven' into the tiles. Theceiling formed by the flanged tiles shown in Figures 3 and 7, may bepainted,

lasteredor otherwise treated, or the ceiling ormingfx'nevtal, boards or-the like may be fastened "to' the tiles.-

4. A tile for concrete floor construction having a rib extending acrossone face thereof adapted to project through a body of concrete placedover said face, and means for positioning a reinforce element extendingtransversely of said rib in spaced relation with respect to both theprojecting surface of said rib and the said surface of said tile.

In testimony whereof I alix my signature.

CHARLES WILLIAM AKERS.

One end'gof the rib'of eachl tile may be y beveled, as shown at11,'these beveled parts forming spaces for reinforcing rods or bars 12placed adjacent the surface of the concrete and which act to preventsurface cracks. In forming this recess 11 in the rib, whether it be atthe end thereof or not, the recess should not extend to the top face ofthe tile. The depth, however, will depend on the height of the rib, thedepth of the recess preferably being such that reinforce elements placedin the recesses will be positioned adjacent the surface of the concrete,as just mentioned.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

What I claim is 1. A tile for a concrete floor structure having anintegral elongated centrall arranged rib, extending longitudinally ofthe top surface of the tile throughout the major portion of the lengthof the tile, said rib being formed of nailable material and adapted toproject through the floor structure, one end of the rib being reduced toform a space for a reinforcing bar.

2. A tile for concrete floor construction havin an elongated rib ofnailable material exten ing substantially entirely across one facethereof, a portion of said rib being removed to form a transversedepression therein for the lacement of a reinforce element.

3. A ti e for concrete floor constructionl havin a rib across one facethereof, a portion o said rib being removed to form a transversedepression for the placement of a reinforce element, the depth of saiddepression being less than the height of the rib to position thereinforce element adjacent the top ment to hub flanges.
